- River levels may increase rapidly in areas of the province on Sunday.
- Environment Canada gave an extreme thunderstorm watch for areas of southern B.C. on Sunday.
Environment Canada has given a fierce thunderstorm watch with the potential of strong winds, large hail, and heavy downpour for areas of southern British Columbia.
The climate agency says the alert is in effect for the Boundary, Nicola, Shuswap, and South Thompson provinces.
The Fraser Canyon — including Lillooet — and the Okanagan Valley — including Kelowna, Vernon, and Penticton — are also incorporated in the watch.
The B.C. River Forecast Centre has issued a high streamflow advisory for the south Interior and southeast part of the region, including Similkameen River, Okanagan and Mission Creek, Boundary, east and West Kootenay, and their tributaries.
A high streamflow advisory implies that river levels are increasing or rising rapidly, but no major flooding is anticipated.
It says there is a possibility for heavy showers and thundershowers in the southern Interior and Kootenays on Sunday and Monday. Growing rivers are anticipated in places that get the heaviest precipitations.
The center says given the delay in the exact areas, and intensity of rainfall, small- and medium-sized watersheds throughout the province may experience high flows on Monday and Tuesday. A flood alert, first issued on June 27, stays in place for Quesnel. A sign means that flooding is expected.
Prophets say people should stay indoors during a thunderstorm and avoid fast-flowing riverbanks when advisories are in place.
